Authors' conclusion

Among adults without ASCVD not taking lipid-lowering therapy at baseline, ASCVD risk for adults with low-normal and high-normal LDL-C, non-HDL-C and apoB was similar, and their risk remained less than in adults with elevated lipoproteins. These findings emphasize the importance of achieving normal atherogenic lipoprotein levels for primary prevention of ASCVD from early adulthood through middle age.

Study context

Population
Adults without atherosclerotic cardiovascular disease (ASCVD) and not taking lipid-lowering therapy at baselinepooled from 3 population-based prospective cohorts
Participants
16,384 adults
Exposure
ASCVD events by baseline LDL-C, non-HDL-C and apoB, including low-normal values

Main finding

As reported in the abstract

Unadjusted ASCVD event incidence · median follow-up of 18.8 years
  • Similar for LDL-C < 70 mg/dL and 70 to 99 mg/dL, and higher with LDL-C ≥ 100 mg/dL; trends similar for non-HDL-C and apoB categories

Observational data: associations, not effects.

Further findings

Outcomeadjusted HR (95% CI)
ASCVD risk (multivariable-adjusted) · median follow-up of 18.8 years — LDL-C < 70 mg/dL vs LDL-C 70 to 99 mg/dL · similar ASCVD risk · after multivariable adjustment1.16 (0.90–1.50)
ASCVD risk (multivariable-adjusted) · median follow-up of 18.8 years — LDL-C ≥ 130 mg/dL vs LDL-C 70 to 99 mg/dL · higher risk · after multivariable adjustment1.31 (1.14–1.50)

ASCVD risk (multivariable-adjusted) · median follow-up of 18.8 years

Adults with non-HDL-C ≥ 160 mg/dL or apoB ≥ 90 mg/dL also had higher risk after multivariable adjustment
